Exhaust advice/MPG questions

Ok so I just picked up a 2006 F250 Fx4 lariat CC. It has the EGR deleted, and a magnaflow exhaust. So far I'm getting high 12s to low 14s in gas mileage. I've read some of the threads on here, but I didn't know if anyone could help me figure out specifically how to get better mileage. I'm not shooting for 20 although I wouldn't turn it down. I was hoping maybe 16 as an average.

Any advice?

How much highway/city driving are you doing?
I am getting around 16mpg average but I run about a 60% hwy/40% city.
Are you in a colder climate where winter fuel will fudge any chance of getting good mileage?
Are you running stock tires? What is you gear ratio?

How about some specifics on the truck. Is it lifted? Got bigger tires? Those will hurt your mileage. That's all I have ever gotten with my truck. I don't have a clue how these guys are claiming higher mileage, but then I have a lifted crew cab long bed with 35's, and it seems to want to run at 80 mph on the highway.

Sorry you guys I should've been more specific. I just got this truck recently. It is not lifted but it is leveled. I am fairly certain it has 3.73 gears. I live in oklahoma so it is cold here right now, yes haha. The tires should be the stock size. It has a magnaflow exhaust. My highway/city driving is about 65-70/35-30 respectively. The tires appear to be street tires as well, not all terrain.

I run just at or below 65 mph, have 3.55 gears with a raised roof van.
It run the xtreme street tune, 155 injectors, studded and a powermax.
In my experience I have found that driving style will lose or gain you 2-3 mpg.
Go with a larger intake, do the blue spring mod, put on an aftermarket FASS or airdog.
But most importantly, drive nice!!

You're going to see poor milage in the Winter. That's the way it it. They add Kero to the Diesel to prevent jelling, and that has the side effect of causing the truck to get worse milage. Also if you're like me, you let her idle a little in the morning to warm up. That burns fuel. If the Idle bumps up when sitting there, that burns more fuel too. If you have to use the 4WD, that's not all that fuel efficient either. All these things, and the ones other's have mentioned, will cause your milage to be poor. You should see an improvement in the Spring. My 7.3L gets 20% better in the warmer months.

Thanks DieselManor.

I really don't mean to be ignorant. I am honestly here to learn as much as I can, and I respect and listen to everything I am told. I'm trying to do as much research as I can. Sadly my long term experience has been with gas engines, very little with diesels. I will have to look into the springs. They don't look like they are too much of a pain to install. I did get my SCT Livewire today, and it has jumped my mpgs up about a solid 1-2 mpg when my foot is out of it.

I'd like to thank all of you for the information, help, and advice. I'm truly grateful.
